Steve Loughran commented on YARN-9057:
--------------------------------------
bq. it it seems to create more problems than the ones it fixed.
Afraid so.
General practise in hadoop-*: unshaded in all our cross references, moving to
shaded for public artifacts (which we still need to do for the object stores).
And we dream of a java9-only world...

> hadoop-yarn-csi-3.3.0-SNAPSHOT.jar bundles all third party classes like a

> for YARN cli:
> {code}
> SLF4J: Class path contains multiple SLF4J bindings.
> SLF4J: Found binding in
